I bought a 2001 Ford focus and it had no works whatsoever except for Aircondition and a CDplayer. I have manual door locks... so my question is, is it possible to make my car have power door locks? I've been getting mixed messages. Please help.

Yeah, you can buy central locking kits through a variety of places, commonly car audio places do them, or electronic shops. Some places will install them as well (for a fee no doubt) or an auto electrician will be able to.

Be sure to buy a kit with the actuators for the door locks and you'll be ok.
